High Intensity Preconditioner (HIP)

Advanced Technology for the Best Mixing Process


The Wenger High Intensity Preconditioner (HIP) provides an advanced level of mixing and control that makes it the perfect complement to Wenger extruders.  Intensified mixing results in smaller particle sizes into the extruder, more uniform product moisture, and more consistent heating.


  • Two independently driven shafts of different sizes
  • Wide range of capacities and retention times
  • Three mixing intensity settings
  • Increases capacity through the extruder
  • Improved pasteurization and sanitation
  • Increased starch gelatinization
  • Reduced product waste at startup/shut down
  • Allows increased addition of meat slurries and other liquids in the recipe

Any process that benefits from higher moistures and longer retention times will benefit from preconditioning

Roll Away Feature


Wenger's unique roll-away feature enables users to bypass the HIP in situations where preconditioning is not required, as dictated by recipe blends or final product characteristics.  


A bypass spout (indicated by the red circle) can be moved into place easily as needed.  


This feature provides excellent flexbility, enabling producers to create a wide range of products using one preconditioner/extruder configuration.
